My computer needed to restart for an OS update. I did so; after restart, all of the currently-showing tabs in Orion (and only those tabs) were in a weird, locked-up state.
More detail: in each Orion window, the tab that is currently displaying is not immediately responsive. For example, if I try to scroll that tab, nothing happens -- until I click away to some other window, and then the tab shows the scrolled view. Similarly, in my Gmail tab, if I click on an email nothing happens -- until I click away, at which point the email that I had clicked on displays.
All other tabs are working fine, and if I open a new tab with the same URL as a locked-up one, that works fine. It's only the tabs that were displaying when I rebooted that are in this strange state.
I don't have time to do another reboot, so I don't know if it easily repros. Updating to MacOS 14.2.1 (23C71) was when this occurred.
Normal functionality.
